so here's an idea:
I have an idea for an NFT collection for true Bitcoin believers.
To get one of these NFTs, you need to prove that you have been keeping 1000 BTC in your wallet for the last 6 months.
This will be verified by you signing a message with your private key and sending it to a smart contract.
First of all, BItcoin doesn't have smart contract. So you probably have to do it on Bitcoin side-chain (such as Rootstock or Liquid) or altcoin with smart contract capability.
So what does everyone think? Is it a dumb idea or should we make it happen?
It's dumb, but nobody can stop you from making it happen.

Why do people buy designer clothes? Why do they wear million-dollar watches?
That also puts a literal target on your back, you just have to make sure your security is on point.
At least those items either have very good branding/popularity, long history or impressive engineering.
